ABSTRACT

It is intended to provide a kit or device for the detection of liver cancer and a method for detecting liver cancer. The present invention relates to a kit or device for the detection of liver cancer, comprising a nucleic acid capable of specifically binding to miRNA in a sample of a subject, and a method for detecting liver cancer, comprising measuring the miRNA in vitro.

TECHNICAL FIELD

The present invention relates to a kit or a device for the detection of liver cancer, comprising a nucleic acid capable of specifically binding to a particular miRNA, which is used for examining the presence or absence of liver cancer in a subject, and a method for detecting liver cancer, comprising measuring an expression level of the miRNA using the nucleic acid.

BACKGROUND ART

The liver is the largest organ in the body and is positioned in the upper right portion of the abdomen. Its main roles are the metabolism of nutrients and the detoxication and elimination of harmful substances. According to the 2011 statistics of cancer types in Japan disclosed by the Center for Cancer Control and Information Services, National Cancer Center, the number of individuals affected by liver cancer is 47,271 people. Namely, it is estimated that one out of every 35 Japanese individuals experience liver cancer. The number of individuals affected by liver cancer among other cancer types takes the 6th in place. Also, men are nearly twice as likely as women to develop liver cancer. The number of liver cancer deaths in men and women together climbed to 30,690 people and takes the 4th in place. An estimate of the number of American individuals affected by liver cancer in 2014 climbs to 33,190 people, among which approximately 23,000 people will die (Non-Patent Literature 1).

In general, primary liver cancer often refers to hepatocellular carcinoma which accounts for approximately 80% of primary liver cancer cases. However, there are other subtypes of primary liver cancer such as intrahepatic bile duct carcinoma which accounts for 10 to 20% of all primary liver cancer cases, and biliary cystadenocarcinoma which is a rarer cancer type.

The stages of liver cancer progression are specified separately for hepatocellular carcinoma and intrahepatic bile duct carcinoma in Non-Patent Literature 2. Herein, particularly, the hepatocellular carcinoma is classified into stage I (T1/N0/M0), stage II (T2/N0/M0), stage IIIA (T3a/NO/M0), stage IIIB (T3b/NO/M0), stage IIIC (T4/NO/M0), stage IVA (N1/M0), and stage IVB (M1) according to the degrees of tumor spread (T0 to T4), lymph node metastasis (N0 and N1), and distant metastasis (M0 and M1).

The 5-year relative survival rate of liver cancer differs depending on the stages of progression. According to Non-Patent Literature 1, the 5-year relative survival rate of liver cancer is reportedly 28% for tumors localized within liver (stage 1, stage 2 and some cases of stage 3), 7% for tumors found to have metastasized to a surrounding area of liver (stage IIIC and stage IVA), and 2% for tumors found to have metastasized distantly (stage IVB). Thus, the detection and treatment of liver cancer at an early stage before metastasis makes a significant contribution to improvement in the survival rate.

The treatment of liver cancer is performed mainly by 3 procedures: surgical therapy mainly involving resection and/or liver transplantation; local therapy which involves injecting a drug through centesis or performing cauterization to kill cancer; and hepatic arterial embolization. These procedures are used in combination with drug therapy or radiotherapy. Particularly, early liver cancer which is found not to metastasize to a blood vessel or an adjacent site is often cured by the partial resection of the liver (Non-Patent Literature 1). On the other hand, even if cancer is localized, liver transplantation is desirable for the cases where such resection is impossible on the ground that the tumors have a large size or are placed in proximity to a blood vessel, for example. If metastasis is found, systemic drug therapy or radiotherapy is performed (Non-Patent Literature 1).

As described in Non-Patent Literature 1, primary tests of liver cancer are inspection and palpation as well as imaging tests such as ultrasonography, CT scan, MRI scan, and angiography. For example, AFP (alpha fetoprotein) and PIVKA-II are known as tumor markers for the detection of liver cancer. The tests using these tumor markers are often performed in combination with ultrasonography. When there are findings that suspect liver cancer by these primary tests, pathological examination which involves inserting a needle into a lesion and collecting cells or tissues, which are then examined under a microscope is carried out as a secondary test.

Meanwhile, it is known that the most important leading cause of liver cancer is prolonged infection with hepatitis B or C virus. Therefore, subjects suspected of having liver cancer may be subjected to a hepatitis virus test in addition to the primary tests described above.

As shown in Patent Literatures 1 to 5, there are reports, albeit at a research stage, on methods for detecting liver cancer using the expression levels of microRNAs (miRNAs) in biological samples including blood and hepatic tissues.

Patent Literature 1 discloses a method for detecting leukemia, breast cancer, and liver cancer using miRNAs: hsa-miR-92a-3p, hsa-miR-92b-3p, hsa-miR-92a-2-5p, and hsa-miR-92b-5p in tissues as markers.

Patent Literature 2 has reported a method for diagnosing various cancers using, as markers, miRNAs such as hsa-miR-23a-3p, hsa-miR-23b-3p, hsa-miR-24-3p, hsa-miR-557, hsa-miR-564, hsa-miR-614, hsa-miR-150-3p, and hsa-miR-486-3p contained in vesicles circulating in body fluids.

Patent Literature 3 discloses a method for detecting various diseases including liver cancer using miRNAs such as hsa-miR-23b-3p, hsa-miR-30c-1-3p, hsa-miR-125a-3p, and hsa-miR-486-3p in tissues or body fluids as markers.

Patent Literature 4 discloses a method for detecting various pathological conditions including liver cancer using, as markers, miRNAs such as hsa-miR-16-5p, hsa-miR-92a-3p, hsa-miR-663a, hsa-miR-1913, and hsa-miR-625-3p, or proteins contained in vesicles circulating in body fluids.

Patent Literature 5 discloses that hsa-miR-187-5p, hsa-miR-92a-3p, hsa-miR-16-5p, and hsa-miR-30c-1-3p in plasma are markers for colorectal cancer, liver cancer, and lung cancer.

SUMMARY OF INVENTION Problem to be Solved by Invention

An object of the present invention is to find a novel tumor marker for liver cancer and to provide a method that can effectively detect liver cancer using a nucleic acid capable of specifically binding to the marker.

Liver cancer progresses without particular symptoms and is therefore difficult to detect early. Since the most part of the liver is housed in the right rib, liver cancer is difficult to detect by palpation. An effective method for liver cancer screening has not yet been established for ordinary people lacking a risk of liver cancer such as hepatitis virus infection or liver cirrhosis (Non-Patent Literature 1). Ultrasonography is a widely prevalent method for liver cancer screening because this method places less burden on patients and is convenient. Nonetheless, liver cancer may be difficult to detect depending on its site of occurrence by ultrasonography. In addition, examination results of ultrasonography largely depend on the skill of technicians. Therefore, it is considered to be desirable that ultrasonography should be used in combination with a tumor marker (Non-Patent Literature 3). Although AFP is known as a tumor marker for the detection of liver cancer, liver cancer found to have an elevated level of AFP is already at an advanced stage and is impossible to resect or has metastasized to an area outside the liver in many cases (Non-Patent Literature 1). It has been reported that some liver cancers do not produce AFP. Meanwhile, AFP is known to also elevate in cancers other than liver cancer, for example, testicular cancer or ovary cancer, and further to elevate in non-cancer liver diseases, for example, sustained hepatitis virus infection, and is therefore regarded as a low specific marker (Non-Patent Literature 1). For example, false diagnosis of other cancers as liver cancer wastes appropriate therapeutic opportunity or places unnecessary economical and physical burdens on patients due to the application of wrong medicine. According to results of large-scale screening research targeting hepatitis B-infected people and prolonged hepatitis patients (Non-Patent Literature 4), the AFP test has liver cancer detection sensitivity as low as 69% and thus has insufficient examination performance for use as a liver cancer screening test. Furthermore, CT scan or MRI scan can detect liver cancer with high performance, but is not suitable as a widely prevalent primary test because these tests require a specific apparatus and high examination cost.

As described below, there are reports, albeit at a research stage, on the determination of liver cancer using the expression levels of microRNAs (miRNAs) in biological samples including blood, none of which, however, have yet been brought into practical use.

Patent Literature 1 discloses a method for detecting leukemia, breast cancer, and liver cancer using miRNAs hsa-miR-92a-3p, hsa-miR-92b-3p, hsa-miR-92a-2-5p, and hsa-miR-92b-5p in blood cells or tissues as markers. This detection method, however, inevitably requires tissue resection by surgical operation for obtaining samples, and this step places a heavy physical burden on patients. Therefore, this method is not favorable as an examination method. In addition, Patent Literature 1 does not describe specific detection performance such as accuracy, sensitivity, or specificity for determining liver cancer as to this detection method, which is thus industrially less practical.

Patent Literature 2 has reported a method for diagnosing various cancers using, as markers, miRNAs such as hsa-miR-23a-3p, hsa-miR-23b-3p, hsa-miR-24-3p, hsa-miR-557, hsa-miR-564, hsa-miR-614, hsa-miR-150-3p, and hsa-miR-486-3p contained in vesicles circulating in body fluids. Patent Literature 2, however, neither describes a specific method for diagnosing liver cancer by use of this detection method nor describes detection performance such as accuracy, sensitivity, or specificity for determining liver cancer. Therefore, this detection method is industrially less practical.

Patent Literature 3 discloses a method for detecting various diseases including liver cancer using miRNAs such as hsa-miR-23b-3p, hsa-miR-30c-1-3p, hsa-miR-125a-3p, and hsa-miR-486-3p in tissues or body fluids as markers. This detection method, however, is based on results of experiments using mouse models, and the detection of liver cancer in humans is unknown about the method. In addition, Patent Literature 3 does not describe detection performance such as accuracy, sensitivity, or specificity for determining liver cancer. Therefore, this detection method is industrially less practical.

Patent Literature 4 discloses a method for detecting various pathological conditions including liver cancer using, as markers, miRNAs such as hsa-miR-16-5p, hsa-miR-92a-3p, hsa-miR-663a, hsa-miR-1913, and hsa-miR-625-3p, or proteins contained in vesicles circulating in body fluids. Patent Literature 4, however, neither describes a specific method for diagnosing liver cancer by use of this detection method nor validated these miRNA markers in an independent sample group. Therefore, this detection method is less reliable.

Patent Literature 5 discloses that hsa-miR-187-5p, hsa-miR-92a-3p, hsa-miR-16-5p, and hsa-miR-30c-1-3p in plasma are markers for colorectal cancer, liver cancer, and lung cancer. These markers, however, are markers for discriminating a group of colorectal cancers from a group of liver cancers, lung cancers, and healthy subjects and is not a marker for detecting liver cancer.

As mentioned above, the existing tumor markers exhibit low performance in the detection of liver cancer, and neither performance nor detection methods are specifically shown as to the markers at a research stage. Therefore, use of these markers might lead to carrying out needless extra examination due to the false detection of healthy subjects as being liver cancer patients, or might waste therapeutic opportunity because of overlooking liver cancer patients. In addition, the measurement of several dozens to several hundreds of miRNAs increases examination cost and is therefore difficult to use in large-scale screening such as medical checkup. Furthermore, the collection of liver tissues for measuring the tumor markers is highly invasive to patients and is not favorable. Hence, there is a demand for a highly accurate liver cancer marker that is detectable from blood, which can be collected with limited invasiveness, and is capable of correctly determining a liver cancer patient as a liver cancer patient and a healthy subject as a healthy subject. Particularly, the early detection and treatment of liver cancer can improve the survival rates. In addition, such liver cancer is often cured by the partial resection of the liver. Therefore, a highly sensitive liver cancer marker capable of detecting liver cancer even at an early stage of progression is desired.

Means for Solution of Problem

The present inventors have conducted diligent studies to attain the object and consequently completed the present invention by finding multiple genes usable as markers for the detection of liver cancer from blood, which can be collected with limited invasiveness, and finding that liver cancer can be significantly detected by using nucleic acid(s) capable of specifically binding to any of these markers.

DEFINITION OF TERM

The terms used herein are defined as follows.

Abbreviations or terms such as nucleotide, polynucleotide, DNA, and RNA abide by “Guidelines for the preparation of specification which contain nucleotide and/or amino acid sequences” (edited by Japan Patent Office) and common use in the art.

The term “polynucleotide” used herein refers to a nucleic acid, including any of RNA, DNA, and RNA/DNA (chimera). The DNA includes any of cDNA, genomic DNA, and synthetic DNA. The RNA includes all of total RNA, mRNA, rRNA, miRNA, siRNA, snoRNA, snRNA, non-coding RNA and synthetic RNA. The “synthetic DNA” and the “synthetic RNA” used herein refer to DNA and RNA artificially prepared using, for example, an automated nucleic acid synthesizer, on the basis of predetermined nucleotide sequences (which may be any of natural and non-natural sequences). The “non-natural sequence” used herein is intended to be used in a broad sense and includes, for example, a sequence containing substitution, deletion, insertion, and/or addition of one or more nucleotide(s) (i.e., a variant sequence) and a sequence containing one or more modified nucleotide(s) (i.e., a modified sequence), which are different from the natural sequence. As used herein, the term “polynucleotide” is used interchangeably with the term “nucleic acid.”

The term “fragment” used herein is a polynucleotide having a nucleotide sequence having a consecutive portion of a polynucleotide and desirably has a length of 15 or more nucleotides, preferably 17 or more nucleotides, more preferably 19 or more nucleotides.

The term “gene” used herein is intended to include not only RNA and double-stranded DNA but also each single-stranded DNA such as a plus strand (or a sense strand) or a complementary strand (or an antisense strand) constituting the duplex. The gene is not particularly limited by its length.

Thus, the “gene” used herein includes all of double-stranded DNA including human genomic DNA, single-stranded DNA (plus strand), single-stranded DNA having a sequence complementary to the plus strand (complementary strand) including cDNA, microRNA (miRNA), and their fragments, and transcripts, unless otherwise specified. The “gene” includes not only a “gene” represented by a particular nucleotide sequence (or SEQ ID NO) but “nucleic acids” encoding RNAs having biological functions equivalent to RNA encoded by the gene, for example, a congener (i.e., a homolog or an ortholog), a variant (e.g., a genetic polymorph), and a derivative. Specific examples of such a “nucleic acid” encoding a congener, a variant, or a derivative can include a “nucleic acid” having a nucleotide sequence hybridizing under stringent conditions described later to a complementary sequence of a nucleotide sequence represented by any of SEQ ID NOs: 1 to 765 or a nucleotide sequence derived from the nucleotide sequence by the replacement of u with t. The “gene” is not particularly limited by its functional region and can contain, for example, an expression regulatory region, a coding region, an exon, or an intron. The “gene” may be contained in a cell or may exist alone after being released into the outside of a cell. Alternatively, the “gene” may be in a state enclosed in a vesicle called exosome.

The term “exosome” used herein is a vesicle that is delimited by a lipid bilayer and secreted from a cell. The exosome is derived from a multivesicular endosome and may incorporate biomaterials such as “gene(s)” (e.g., RNA or DNA) or protein(s) when released into an extracellular environment. The exosome is known to be contained in a body fluid such as blood, serum, plasma, serum, or lymph.

The term “transcript” used herein refers to RNA synthesized from the DNA sequence of a gene as a template. RNA polymerase binds to a site called a promoter located upstream of the gene and adds ribonucleotides complementary to the nucleotide sequence of the DNA to the 3′ end to synthesize RNA. This RNA contains not only the gene itself but also the whole sequence from a transcription initiation site to the end of a polyA sequence, including an expression regulatory region, a coding region, an exon, or an intron.

The term “microRNA (miRNA)” used herein is intended to mean a 15- to 25-nucleotide non-coding RNA that is transcribed as an RNA precursor having a hairpin-like structure, cleaved by a dsRNA-cleaving enzyme which has RNase III cleavage activity, and integrated into a protein complex called RISC, and involved in the suppression of translation of mRNA, unless otherwise specified. The term “miRNA” used herein includes not only a “miRNA” represented by a particular nucleotide sequence (or SEQ ID NO) but a precursor of the “miRNA” (pre-miRNA or pri-miRNA), and miRNAs having biological functions equivalent thereto, for example, a congener (i.e., a homolog or an ortholog), a variant (e.g., a genetic polymorph), and a derivative. Such a precursor, a congener, a variant, or a derivative can be specifically identified using miRBase Release 20 (http://www.mirbase.org/), and examples thereof can include a “miRNA” having a nucleotide sequence hybridizing under stringent conditions described later to a complementary sequence of any particular nucleotide sequence represented by any of SEQ ID NOs: 1 to 765. The term “miRNA” used herein may be a gene product of a miR gene. Such a gene product includes a mature miRNA (e.g., a 15- to 25-nucleotide or 19- to 25-nucleotide non-coding RNA involved in the suppression of translation of mRNA as described above) or a miRNA precursor (e.g., pre-miRNA or pri-miRNA as described above).

The term “probe” used herein includes a polynucleotide that is used for specifically detecting RNA resulting from the expression of a gene or a polynucleotide derived from the RNA, and/or a polynucleotide complementary thereto.

The term “primer” used herein includes a polynucleotide that specifically recognizes and amplifies RNA resulting from the expression of a gene or a polynucleotide derived from the RNA, and/or a polynucleotide complementary thereto.

In this context, the complementary polynucleotide (complementary strand or reverse strand) means a polynucleotide in a complementary relationship of A:T (U) and G:C base pairs with the full-length sequence of a polynucleotide consisting of a nucleotide sequence defined by any of SEQ ID NOs: 1 to 765 or a nucleotide sequence derived from the nucleotide sequence by the replacement of u with t, or a partial sequence thereof (here, this full-length or partial sequence is referred to as a plus strand for the sake of convenience). However, such a complementary strand is not limited to a sequence completely complementary to the nucleotide sequence of the target plus strand and may have a complementary relationship to an extent that permits hybridization under stringent conditions to the target plus strand.

The term “stringent conditions” used herein refers to conditions under which a nucleic acid probe hybridizes to its target sequence to a larger extent (e.g., a measurement value equal to or larger than a mean of background measurement values+a standard deviation of the background measurement values×2) than that for other sequences. The stringent conditions are dependent on a sequence and differ depending on an environment where hybridization is performed. A target sequence that is 100% complementary to the nucleic acid probe can be identified by controlling the stringency of hybridization and/or washing conditions. Specific examples of the “stringent conditions” is mentioned later.

The term “Tm value” used herein means a temperature at which the double-stranded moiety of a polynucleotide is denatured into single strands so that the double strands and the single strands exist at a ratio of 1:1.

The term “variant” used herein means, in the case of a nucleic acid, a natural variant attributed to polymorphism, mutation, or the like; a variant containing the deletion, substitution, addition, or insertion of 1 or 2 or more nucleotides in a nucleotide sequence represented by any of SEQ ID NOs: 1 to 765 or a nucleotide sequence derived from the nucleotide sequence by the replacement of u with t, or a partial sequence thereof; a variant that exhibits percent (%) identity of approximately 90% or higher, approximately 95% or higher, approximately 97% or higher, approximately 98% or higher, approximately 99% or higher to each of these nucleotide sequences or the partial sequence thereof; or a nucleic acid hybridizing under the stringent conditions defined above to a polynucleotide or an oligonucleotide comprising each of these nucleotide sequences or the partial sequence thereof.

The term “several” used herein means an integer of approximately 10, 9, 8, 7, 6, 5, 4, 3, or 2.

The variant used herein can be prepared by use of a well-known technique such as site-directed mutagenesis or PCR-based mutagenesis.

The term “percent (%) identity” used herein can be determined with or without an introduced gap, using a protein or gene search system based on BLAST or FASTA described above (Zheng Zhang et al., 2000, J. Comput. Biol., Vol. 7, p. 203-214; Altschul, S. F. et al., 1990, Journal of Molecular Biology, Vol. 215, p. 403-410; and Pearson, W. R. et al., 1988, Proc. Natl. Acad. Sci. U.S.A, Vol. 85, p. 2444-2448).

The term “derivative” used herein is meant to include a modified nucleic acid, for example, a derivative labeled with a fluorophore or the like, a derivative containing a modified nucleotide (e.g., a nucleotide containing a group such as halogen, alkyl such as methyl, alkoxy such as methoxy, thio, or carboxymethyl, and a nucleotide that has undergone base rearrangement, double bond saturation, deamination, replacement of an oxygen molecule with a sulfur atom, etc.), PNA (peptide nucleic acid; Nielsen, P. E. et al., 1991, Science, Vol. 254, p. 1497-500), and LNA (locked nucleic acid; Obika, S. et al., 1998, Tetrahedron Lett., Vol. 39, p. 5401-5404) without any limitation.

As used herein, the “nucleic acid” capable of specifically binding to a polynucleotide selected from the group of the miRNAs described above which are the liver cancer markers is a synthesized or prepared nucleic acid and specifically includes a “nucleic acid probe” or a “primer”. The “nucleic acid” is utilized directly or indirectly for detecting the presence or absence of liver cancer in a subject, for diagnosing the presence or absence of liver cancer, the severity of liver cancer, the presence or absence of amelioration or the degree of amelioration of liver cancer, or the therapeutic sensitivity of liver cancer, or for screening for a candidate substance useful in the prevention, amelioration, or treatment of liver cancer. The “nucleic acid” includes a nucleotide, an oligonucleotide, and a polynucleotide capable of specifically recognizing and binding to a transcript represented by any of SEQ ID NOs: 1 to 765 or a synthetic cDNA nucleic acid thereof in vivo, particularly, in a sample such as a body fluid (e.g., blood or urine), in relation to the development of liver cancer. The nucleotide, the oligonucleotide, and the polynucleotide can be effectively used as probes for detecting the aforementioned gene expressed in vivo, in tissues, in cells, or the like on the basis of the properties described above, or as primers for amplifying the aforementioned gene expressed in vivo.

The term “detection” used herein is interchangeable with the term “examination”, “measurement”, “detection” or “decision support”. The term “evaluation” used herein is meant to include diagnosis or evaluation support on the basis of examination results or measurement results.

The term “subject” used herein means a mammal such as a primate including a human and a chimpanzee, a pet animal including a dog and a cat, a livestock animal including cattle, a horse, sheep, and a goat, and a rodent including a mouse and a rat. The term “healthy subject” also means such a mammal without the cancer to be detected.

The term “liver cancer” used herein means “primary liver cancer”, which develops primarily in the liver. The liver cancer includes, for example, “hepatocellular carcinoma” and “combined hepatocellular and cholangiocellular carcinoma” caused by the malignant transformation of cells of the liver.

The term “P” or “P value” used herein refers to a probability at which a more extreme statistic than that actually calculated from data under null hypothesis is observed in a statistical test. Thus, smaller “P” or “P value” is regarded as being more significant difference between subjects to be compared.

The term “sensitivity” used herein means a value of (the number of true positives)/(the number of true positives+the number of false negatives). High sensitivity allows liver cancer to be detected early, leading to the complete resection of cancer sites and reduction in the rate of recurrence.

The term “specificity” used herein means a value of (the number of true negatives)/(the number of true negatives+the number of false positives). High specificity prevents needless extra examination for healthy subjects misjudged as being liver cancer patients, leading to reduction in burden on patients and reduction in medical expense.

The term “accuracy” used herein means a value of (the number of true positives+the number of true negatives)/(the total number of cases). The accuracy indicates the ratio of samples that are correctly identified in the discriminant results to all samples, and serves as a primary index for evaluating detection performance.

As used herein, the “sample” that is subjected to determination, detection, or diagnosis refers to a tissue and a biological material in which the expression of the gene of the present invention varies as liver cancer develops, as liver cancer progresses, or as therapeutic effects on liver cancer are exerted. Specifically, the “sample” refers to a hepatic tissue, a perihepatic vascular channel, lymph node, and organ, an organ suspected of having metastasis, the skin, a body fluid such as blood, urine, saliva, sweat, or tissue exudates, serum or plasma prepared from blood, feces, hair, and the like. The “sample” further refers to a biological sample extracted therefrom, specifically, a gene such as RNA or miRNA.

Advantageous Effects of Invention

According to the present invention, liver cancer can be detected easily and highly accurately. For example, the presence or absence of liver cancer in a patient can be easily detected by using, as an indicator, the measurement values of several miRNAs in blood, serum, and/or plasma of the patient, which can be collected with limited invasiveness.

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 This figure shows the relationship between the nucleotide sequences of hsa-miR-1343-5p represented by SEQ ID NO: 131 and hsa-miR-1343-3p represented by SEQ ID NO: 1, which are produced from a precursor hsa-mir-1343 represented by SEQ ID NO: 225.

FIG. 2 Left diagram: the measurement values of hsa-miR-1343-3p (SEQ ID NO: 1) in healthy subjects (100 persons) and liver cancer patients (34 persons) selected as a training cohort were each plotted on the ordinate. The horizontal line in the diagram depicts a threshold (7.09) that was optimized by Fisher's linear discriminant analysis and discriminated between the two groups. Right diagram: the measurement values of hsa-miR-1343-3p (SEQ ID NO: 1) in healthy subjects (50 persons) and liver cancer patients (16 persons) selected as a validation cohort were each plotted on the ordinate. The horizontal line in the diagram depicts the threshold (7.09) that was set in the training cohort and discriminated between the two groups.

FIG. 3 Left diagram: the measurement values of hsa-miR-1343-3p (SEQ ID NO: 1) in healthy subjects (100 persons, circles) and liver cancer patients (34 persons, triangles) selected as a training cohort were each plotted on the abscissa against their measurement values of hsa-miR-6′726-5p (SEQ ID NO: 2) on the ordinate. The line in the diagram depicts a discriminant function (0=0.77x+y−15.07) that was optimized by Fisher's linear discriminant analysis and discriminated between the two groups. Right diagram: the measurement values of hsa-miR-1343-3p (SEQ ID NO: 1) in healthy subjects (50 persons, circles) and liver cancer patients (16 persons, triangles) selected as a validation cohort were each plotted on the abscissa against their measurement values of hsa-miR-6726-5p (SEQ ID NO: 2) on the ordinate. The line in the diagram depicts the threshold (0=0.77x+y−15.07) that was set in the training cohorts and discriminated between the two groups.

FIG. 4 Upper diagram: a discriminant (0.88×hsa-miR-6131-1.58×hsa-miR-642a-3p+0.39×hsa-miR-7641-0.33×hsa-miR-6729-5p+5.19) was prepared by use of Fisher's linear discriminant analysis from the measurement values of hsa-miR-6131 (SEQ ID NO: 7), hsa-miR-642a-3p (SEQ ID NO: 148), hsa-miR-7641 (SEQ ID NO: 9), and hsa-miR-6′729-5p (SEQ ID NO: 27) in 35 liver cancer patients, 99 healthy subjects, 72 pancreatic cancer patients, 61 bile duct cancer patients, 35 colorectal cancer patients, 38 stomach cancer patients, 25 esophageal cancer patients, and 16 benign pancreaticobiliary disease patients selected as a training cohort, and discriminant scores obtained from the discriminant were plotted on the ordinate against the sample groups on the abscissa. The dotted line in the diagram depicts a discriminant boundary that offered a discriminant score of 0 and discriminated between the groups. Lower diagram: discriminant scores obtained from the discriminant prepared from the training cohorts as to the measurement values of hsa-miR-6131 (SEQ ID NO: 7), hsa-miR-642a-3p (SEQ ID NO: 148), hsa-miR-7641 (SEQ ID NO: 9), and hsa-miR-6729-5p (SEQ ID NO: 27) in 17 liver cancer patients, 51 healthy subjects, 28 pancreatic cancer patients, 37 bile duct cancer patients, 15 colorectal cancer patients, 12 stomach cancer patients, 25 esophageal cancer patients, and 5 benign pancreaticobiliary disease patients selected as a validation cohort were plotted on the ordinate against the sample groups on the abscissa. The dotted line in the diagram depicts the discriminant boundary that offered a discriminant score of 0 and discriminated between the two groups.

Therefore, each polynucleotide that can be used as a nucleic acid probe or a primer in the present invention can be prepared by cloning the gene.

Such a nucleic acid probe or a primer can be chemically synthesized using an automated DNA synthesizer. In general, a phosphoramidite method is used in this synthesis, and single-stranded DNA up to approximately 100 nucleotides can be automatically synthesized by this method. The automated DNA synthesizer is commercially available from, for example, Polygen GmbH, ABI, or Applied Biosystems, Inc.

Alternatively, the polynucleotide of the present invention can also be prepared by a cDNA cloning method. The cDNA cloning technique can employ, for example, microRNA Cloning Kit Wako.

In this context, the sequences of the nucleic acid probe and the primer for detecting the polynucleotide consisting of a nucleotide sequence represented by any of SEQ ID NOs: 1 to 224 and 714 to 729 do not exist as miRNAs or precursors thereof in vivo. For example, the nucleotide sequences represented by SEQ ID NO: 1 and SEQ ID NO: 131 are produced from the precursor represented by SEQ ID NO: 225. This precursor has a hairpin-like structure as shown in FIG. 1, and the nucleotide sequences represented by SEQ ID NO: 1 and SEQ ID NO: 131 have mismatch sequences with each other. Therefore, a nucleotide sequence completely complementary to the nucleotide sequence represented by SEQ ID NO: 1 or SEQ ID NO: 131 is not naturally produced in vivo.

This method of the present invention enables a limitedly invasive, early diagnosis of the cancer with high sensitivity and high specificity and thereby brings about early treatment and improved prognosis. In addition, exacerbation of the disease or the effectiveness of surgical, radiotherapeutic, and chemotherapeutic treatments can be monitored.

The method for extracting the liver cancer-derived gene from the sample such as blood, serum, or plasma according to the present invention is particularly preferably prepared by the addition of a reagent for RNA extraction in 3D-Gene® RNA extraction reagent from liquid sample kit (Toray Industries, Inc.). A general acidic phenol method (acid guanidinium-phenol-chloroform (AGPC)) may be used, or Trizol® (Life Technologies Corp.) may be used. The liver cancer-derived gene may be prepared by the addition of a reagent for RNA extraction containing acidic phenol, such as Trizol (Life Technologies Corp.) or Isogen (Nippon Gene Co., Ltd.). Alternatively, a kit such as miRNeasy® Mini Kit (Qiagen N.V.) can be used, though the method is not limited thereto.

The present invention also provides use of the kit or the device of the present invention for detecting in vitro an expression product of a liver cancer-derived miRNA gene in a sample derived from a subject.

In the method of the present invention, the kit or device described above comprising a single polynucleotide or any possible combination of the polynucleotides that can be used in the present invention as described above is used.

In the detection or (genetic) diagnosis of liver cancer according to the present invention, each polynucleotide contained in the kit or the device of the present invention can be used as a probe or a primer. In the case of using the polynucleotide as a primer, TaqMan® MicroRNA Assays from Life Technologies Corp., miScript PCR System from Qiagen N.V., or the like can be used, though the method is not limited thereto.

The polynucleotide contained in the kit or the device of the present invention can be used as a primer or a probe according to a routine method in a method known in the art for specifically detecting the particular gene, for example, a hybridization technique such as Northern blot, Southern blot, in situ hybridization, Northern hybridization, or Southern hybridization, or a quantitative amplification technique such as quantitative RT-PCR. A body fluid such as blood, serum, plasma, or urine of the subject is collected as a sample to be assayed according to the type of the detection method used. Alternatively, total RNA prepared from such a body fluid by the method described above may be used, and various polynucleotides including cDNA prepared on the basis of the RNA may be used.

The kit or the device of the present invention is useful for the diagnosis of liver cancer or the detection of the presence or absence of liver cancer. Specifically, the detection of liver cancer using the kit or the device can be performed by detecting in vitro an expression level of a gene using the nucleic acid probe or the primer contained in the kit or the device in a sample such as blood, serum, plasma, or urine from a subject suspected of having liver cancer. The subject suspected of having liver cancer can be evaluated as having liver cancer when the expression level of a target miRNA marker measured using polynucleotide(s) (including variant(s), fragment(s), and derivative(s) thereof) consisting of a nucleotide sequence represented by at least one or more of SEQ ID NOs: 1 to 167 and 714 to 729 or a complementary sequence thereof, optionally a nucleotide sequence represented by one or more of SEQ ID NOs: 168 to 183 or a complementary sequence thereof, and optionally a nucleotide sequence represented by one or more of SEQ ID NOs: 184 to 224 or a complementary sequence thereof in the sample such as blood, serum, plasma, or urine of the subject is statistically significantly different compared with the expression level thereof in the sample such as blood, serum, or plasma, or urine of a healthy subject.

The method of the present invention can be combined with a diagnostic imaging method such as ultrasonography, CT scanning, MRI scanning, or angiography examination. The method of the present invention is capable of specifically detecting liver cancer and can substantially discriminate liver cancer from the other cancers.

The method for detecting the absence of an expression product of a liver cancer-derived gene or the presence of the expression product of a liver cancer-derived gene in a sample using the kit or the device of the present invention comprises collecting a body fluid such as blood, serum, plasma, or urine of a subject, and measuring the expression level of the target gene contained therein using one or more polynucleotide(s) (including variant(s), fragment(s), or derivative(s)) selected from the polynucleotide group of the present invention, to evaluate the presence or absence of liver cancer or to detect liver cancer. Using the method for detecting liver cancer according to the present invention, for example, the presence or absence of amelioration of the disease or the degree of amelioration thereof in a liver cancer patient when a therapeutic drug is administered to the patient for amelioration of the disease can be also evaluated or diagnosed.

The method of the present invention may comprise, for example, the following steps (a), (b), and (c):

(a) a step of contacting in vitro a sample derived from a subject with a polynucleotide in the kit or the device of the present invention;

(b) a step of measuring an expression level of the target nucleic acid in the sample using the polynucleotide as a nucleic acid probe or a primer; and

(c) a step of evaluating the presence or absence of liver cancer (cells) in the subject on the basis of a measurement result obtained in the step (b).

Specifically, the present invention provides a method for detecting liver cancer, comprising measuring an expression level of a target nucleic acid in a sample of a subject using nucleic acid(s) capable of specifically binding to at least one or more (preferably at least two or more) polynucleotide(s) selected from the group consisting of miR-1343-3p, miR-6726-5p, miR-6515-3p, miR-4651, miR-4257, miR-3188, miR-6131, miR-6766-3p, miR-7641, miR-1249, miR-3679-3p, miR-6787-5p, miR-4454, miR-3135b, miR-6765-3p, miR-7975, miR-204-3p, miR-7977, miR-7110-5p, miR-6717-5p, miR-6870-5p, miR-663b, miR-6875-5p, miR-8072, miR-6816-5p, miR-4281, miR-6729-5p, miR-8069, miR-4706, miR-7108-5p, miR-4433b-3p, miR-6893-5p, miR-6857-5p, miR-1227-5p, miR-6741-5p, miR-451a, miR-8063, miR-3622a-5p, miR-615-5p, miR-128-1-5p, miR-6825-5p, miR-1260b, miR-4433-3p, miR-4665-5p, miR-7845-5p, miR-1908-5p, miR-6840-3p, miR-6765-5p, miR-296-5p, miR-3675-3p, miR-6781-5p, miR-423-5p, miR-3663-3p, miR-6784-5p, miR-6749-5p, miR-1231, miR-4746-3p, miR-6780b-5p, miR-4758-5p, miR-3679-5p, miR-3184-5p, miR-6125, miR-6721-5p, miR-6791-5p, miR-3185, miR-1260a, miR-3197, miR-6845-5p, miR-6887-5p, miR-6738-5p, miR-6872-3p, miR-4497, miR-1229-5p, miR-6820-5p, miR-6777-5p, miR-3917, miR-5787, miR-4286, miR-6877-5p, miR-1225-3p, miR-6088, miR-6800-5p, miR-1246, miR-4467, miR-4419b, miR-1914-3p, miR-4632-5p, miR-1915-5p, miR-3940-5p, miR-1185-2-3p, miR-6746-5p, miR-5001-5p, miR-1228-5p, miR-5572, miR-4327, miR-4638-5p, miR-6799-5p, miR-6861-5p, miR-6727-5p, miR-4513, miR-6805-3p, miR-6808-5p, miR-4449, miR-1199-5p, miR-1275, miR-4792, miR-4443, miR-6891-5p, miR-6826-5p, miR-6807-5p, miR-7150, miR-4534, miR-4476, miR-4649-5p, miR-4525, miR-1915-3p, miR-4516, miR-4417, miR-642b-3p, miR-3141, miR-5100, miR-6848-5p, miR-4739, miR-4459, miR-1237-5p, miR-296-3p, miR-4665-3p, miR-6786-5p, miR-4258, miR-6510-5p, miR-1343-5p, miR-1247-3p, miR-6805-5p, miR-4492, miR-1469, miR-1268b, miR-6858-5p, miR-3937, miR-939-5p, miR-3656, miR-744-5p, miR-4687-3p, miR-4763-3p, miR-3620-5p, miR-3195, miR-6842-5p, miR-4707-5p, miR-642a-3p, miR-7113-3p, miR-4728-5p, miR-5195-3p, miR-1185-1-3p, miR-6774-5p, miR-8059, miR-3131, miR-7847-3p, miR-4463, miR-128-2-5p, miR-4508, miR-6806-5p, miR-7111-5p, miR-6782-5p, miR-4734, miR-3162-5p, miR-887-3p, miR-6752-5p, miR-6724-5p, miR-6757-5p, miR-4448, miR-671-5p, miR-3178, miR-4725-3p, miR-940, miR-6789-5p, miR-4484, miR-4634, miR-4745-5p, miR-4730, miR-6803-5p, miR-6798-5p, miR-3648, miR-4783-3p and miR-6836-3p, and evaluating in vitro whether or not the subject has liver cancer using the measured expression level and a control expression level of a healthy subject measured in the same way as above.

In a preferred embodiment, such a nucleic acid is specifically a polynucleotide selected from the group consisting of the following polynucleotides (k) to (o):

(k) a polynucleotide consisting of a nucleotide sequence represented by any of SEQ ID NOs: 184 to 224 or a nucleotide sequence derived from the nucleotide sequence by the replacement of u with t, a variant thereof, a derivative thereof, or a fragment thereof comprising 15 or more consecutive nucleotides, (l) a polynucleotide comprising a nucleotide sequence represented by any of SEQ ID NOs: 184 to 224, (m) a polynucleotide consisting of a nucleotide sequence complementary to a nucleotide sequence represented by any of SEQ ID NOs: 184 to 224 or a nucleotide sequence derived from the nucleotide sequence by the replacement of u with t, a variant thereof, a derivative thereof, or a fragment thereof comprising 15 or more consecutive nucleotides, (n) a polynucleotide comprising a nucleotide sequence complementary to a nucleotide sequence represented by any of SEQ ID NOs: 184 to 224 or a nucleotide sequence derived from the nucleotide sequence by the replacement of u with t, and (o) a polynucleotide hybridizing under stringent conditions to any of the polynucleotides (k) to (n).

Examples of the sample used in the method of the present invention can include samples prepared from a living tissue (preferably a liver tissue) or a body fluid such as blood, serum, plasma, or urine of the subject. Specifically, for example, an RNA-containing sample prepared from the tissue, a polynucleotide-containing sample further prepared therefrom, a body fluid such as blood, serum, plasma, or urine, a portion or the whole of a living tissue collected from the subject by biopsy or the like, or a living tissue excised by surgery can be used, and the sample for measurement can be prepared therefrom.

The subject used herein refers to a mammal, for example, a human, a monkey, a mouse and a rat without any limitation, and is preferably a human.

The steps of the method of the present invention can be changed according to the type of the sample to be assayed.

In the case of using RNA as an analyte, the detection of liver cancer (cells) may comprise, for example, the following steps (a), (b), and (c):

(a) a step of binding RNA prepared from the sample of a subject or a complementary polynucleotide (cDNA) transcribed therefrom to a polynucleotide in the kit or the device of the present invention;

(b) a step of measuring the sample-derived RNA or the cDNA synthesized from the RNA, bound with the polynucleotide by hybridization using the polynucleotide as a nucleic acid probe or by quantitative RT-PCR using the polynucleotide as a primer; and

(c) a step of evaluating the presence or absence of liver cancer (or liver cancer-derived gene expression) on the basis of the measurement results of the step (b).

For example, various hybridization methods can be used for detecting, examining, evaluating, or diagnosing liver cancer (or liver cancer-derived gene expression) in vitro according to the present invention. For example, Northern blot, Southern blot, RT-PCR, DNA chip analysis, in situ hybridization, Northern hybridization, or Southern hybridization can be used as such a hybridization method.

In the case of using the Northern blot, the presence or absence of expression of each gene or the expression level thereof in the RNA can be detected or measured by use of the nucleic acid probe that can be used in the present invention. Specific examples thereof can include a method which comprises labeling the nucleic acid probe (a complementary strand) with a radioisotope (³²P, ³³P, ³⁵S, etc.), a fluorescent material, or the like, hybridizing the labeled product with the living tissue-derived RNA from the subject, which is transferred to a nylon membrane or the like according to a routine method, and then detecting and measuring a signal derived from the label (radioisotope or fluorescent material) on the formed DNA/RNA duplex using a radiation detector (examples thereof can include BAS-1800 II (Fujifilm Corp.)) or a fluorescence detector (examples thereof can include STORM 865 (GE Healthcare Japan Corp.)).

In the case of using the quantitative RT-PCR, the presence or absence of expression of each gene or the expression level thereof in the RNA can be detected or measured by use of the primer that can be used in the present invention. Specific examples thereof can include a method which comprises preparing cDNA from the living tissue-derived RNA of the subject according to a routine method, hybridizing a pair of primers (consisting of a plus strand and a reverse strand binding to the cDNA) of the present invention with the cDNA such that the region of each target gene can be amplified with the cDNA as a template, and performing PCR according to a routine method to detect the obtained double-stranded DNA. The method for detecting the double-stranded DNA can include a method of performing the PCR using the primers labeled in advance with a radioisotope or a fluorescent material, a method of electrophoresing the PCR product on an agarose gel and staining the double-stranded DNA with ethidium bromide or the like for detection, and a method of transferring the produced double-stranded DNA to a nylon membrane or the like according to a routine method and hybridizing the double-stranded DNA to a labeled nucleic acid probe for detection.

In the case of using the nucleic acid array analysis, an RNA chip or a DNA chip in which the nucleic acid probes (single-stranded or double-stranded) of the present invention are attached to a substrate (solid phase) is used. Regions having the attached nucleic acid probes are referred to as probe spots, and regions having no attached nucleic acid probe are referred to as blank spots. A group of genes immobilized on a solid-phase substrate is generally called a nucleic acid chip, a nucleic acid array, a microarray, or the like. The DNA or RNA array includes a DNA or RNA macroarray and a DNA or RNA microarray. The term “chip” used herein includes all of them. 3D-Gene® Human miRNA Oligo chip (Toray Industries, Inc.) can be used as the DNA chip, though the DNA chip is not limited thereto.

Examples of the measurement using the DNA chip can include, but are not limited to, a method of detecting and measuring a signal derived from the label on the nucleic acid probes using an image detector (examples thereof can include Typhoon 9410 (GE Healthcare Japan Corp.) and 3D-Gene® scanner (Toray Industries, Inc.)).

The “stringent conditions” used herein are, as mentioned above, conditions under which a nucleic acid probe hybridizes to its target sequence to a larger extent (e.g., a measurement value equal to or larger than a mean of background measurement values+a standard deviation of the background measurement values×2) than that for other sequences.

The stringent conditions are defined by hybridization and subsequent washing conditions. Examples of the hybridization conditions include, but not limited to, 30° C. to 60° C. for 1 to 24 hours in a solution containing SSC, a surfactant, formamide, dextran sulfate, a blocking agent, etc. In this context, 1×SSC is an aqueous solution (pH 7.0) containing 150 mM sodium chloride and 15 mM sodium citrate. The surfactant includes, for example, SDS (sodium dodecyl sulfate), Triton, or Tween. The hybridization conditions more preferably comprise 3 to 10×SSC and 0.1 to 1% SDS. Examples of the conditions for the washing, following the hybridization, which is another condition to define the stringent conditions, can include conditions comprising continuous washing at 30° C. in a solution containing 0.5×SSC and 0.1% SDS, at 30° C. in a solution containing 0.2×SSC and 0.1% SDS, and at 30° C. in a 0.05×SSC solution. It is desirable that the complementary strand should maintain its hybridized state with a target plus strand even by washing under such conditions. Specifically, examples of such a complementary strand can include a strand consisting of a nucleotide sequence in a completely complementary relationship with the nucleotide sequence of the target plus strand, and a strand consisting of a nucleotide sequence having at least 80%, preferably at least 85%, more preferably at least 90% or at least 95%, for example, at least 98% or at least 99% identity to the strand.

Other examples of the “stringent conditions” for the hybridization are described in, for example, Sambrook, J. & Russel, D., Molecular Cloning, A LABORATORY MANUAL, Cold Spring Harbor Laboratory Press, published on Jan. 15, 2001, Vol. 1, 7.42 to 7.45 and Vol. 2, 8.9 to 8.17, and can be used in the present invention.

Examples of the conditions for carrying out PCR using a polynucleotide fragment in the kit of the present invention as a primer include treatment for approximately 15 seconds to 1 minute at 5 to 10° C. plus a Tm value calculated from the sequence of the primer, using a PCR buffer with composition such as 10 mM Tris-HCL (pH 8.3), 50 mM KCL, and 1 to 2 mM MgCl₂. Examples of the method for calculating such a Tm value include Tm value=2×(the number of adenine residues+the number of thymine residues)+4×(the number of guanine residues+the number of cytosine residues).

In the case of using the quantitative RT-PCR, a commercially available kit for measurement specially designed for quantitatively measuring miRNA, such as TaqMan® MicroRNA Assays (Life Technologies Corp.); LNA®-based MicroRNA PCR (Exiqon); or Ncode® miRNA qRT-PCT kit (Invitrogen Corp.) may be used.

For the calculation of gene expression levels, statistical treatment described in, for example, Statistical analysis of gene expression microarray data (Speed T., Chapman and Hall/CRC), and A beginner's guide Microarray gene expression data analysis (Causton H. C. et al., Blackwell publishing) can be used in the present invention, though the calculation method is not limited thereto. For example, twice, preferably 3 times, more preferably 6 times the standard deviation of the measurement values of the blank spots are added to the average measurement value of the blank spots on the DNA chip, and probe spots having a signal value equal to or larger than the resulting value can be regarded as detection spots. Alternatively, the average measurement value of the blank spots is regarded as a background and can be subtracted from the measurement values of the probe spots to determine gene expression levels. A missing value for a gene expression level can be excluded from the analyte, preferably replaced with the smallest value of the gene expression level in each DNA chip, or more preferably replaced with a value obtained by subtracting 0.1 from a logarithmic value of the smallest value of the gene expression level. In order to eliminate low-signal genes, only a gene having a gene expression level of 2⁶, preferably 2⁸, more preferably 2¹⁰ or larger in 20% or more, preferably 50% or more, more preferably 80% or more of the number of measurement samples can be selected as the analyte. Examples of the normalization of the gene expression level include, but are not limited to, global normalization and quantile normalization (Bolstad, B. M. et al., 2003, Bioinformatics, Vol. 19, p. 185-193).

The present invention also provides a method comprising measuring a target gene or gene expression level in a sample derived from a subject using the polynucleotide, the kit, or the device (e.g., chip) for detection of the present invention, or a combination thereof, preparing a discriminant (discriminant function) with gene expression levels in a sample derived from a liver cancer patient and a sample derived from a healthy subject as supervising samples, and determining or evaluating the presence and/or absence of the liver cancer-derived gene in the sample.

Specifically, the present invention further provides the method comprising: a first step of measuring in vitro an expression level of a target gene (target nucleic acids) in multiple samples known to determine or evaluate the presence or absence of the liver cancer-derived gene in the samples, using the polynucleotide, the kit, or the device (e.g., chip) for detection of the present invention, or a combination thereof; a second step of constructing a discriminant with the measurement values of the expression level of the target gene obtained in the first step as supervising samples; a third step of measuring in vitro an expression level of the target gene in a sample derived from a subject in the same way as in the first step; and a fourth step of substituting the measurement value of the expression level of the target gene obtained in the third step into the discriminant obtained in the second step, and determining or evaluating the presence or absence of the liver cancer-derived gene in the sample on the basis of the results obtained from the discriminant, wherein the target gene can be detected using the polynucleotide or using a polynucleotide for detection contained in the kit or the device (e.g., chip). In this context, the discriminant can be prepared by use of Fisher's linear discriminant analysis, nonlinear discriminant analysis based on Mahalanobis' distance, neural network, Support Vector Machine (SVM), or the like, though the method is not limited thereto.

When a clustering boundary is a straight line or a hyperplane, the linear discriminant analysis is a method for determining the association of a cluster using Formula 1 as a discriminant. In this formula, x represents an explanatory variable, w represents a coefficient of the explanatory variable, and w₀ represents a constant term.

$\begin{matrix} {{f(x)} = {w_{0} + {\sum\limits_{i = 1}^{n}\;{w_{i}x_{i}}}}} & {{Formula}\mspace{14mu} 1} \end{matrix}$

Values obtained from the discriminant are referred to as discriminant scores. The measurement values of a newly offered data set can be substituted as explanatory variables into the discriminant to determine clusters on the basis of the signs of the discriminant scores.

The Fisher's linear discriminant analysis, one type of linear discriminant analysis, is a dimensionality reduction method for selecting a dimension suitable for discriminating classes, and constructs a highly discriminating synthetic variable by focusing on the variance of the synthetic variables and minimizing the variance of data having the same label (Venables, W. N. et al., Modern Applied Statistics with S. Fourth edition. Springer., 2002). In the Fisher's linear discriminant analysis, direction w of projection is determined so as to maximize Formula 2. In this formula, μ represents an average input, ng represents the number of data associated with class g, and μg represents an average input of the data associated with class g. The numerator and the denominator are interclass variance and intraclass variance, respectively, when each data is projected in the direction of the vector w. Discriminant coefficient wi is determined by maximizing this ratio (Takafumi Kanamori et al., “Pattern Recognition”, Kyoritsu Shuppan Co., Ltd. (2009); and Richard O. et al., Pattern Classification Second Edition., Wiley-Interscience, 2000).

$\begin{matrix} {{{J(w)} = \frac{\sum\limits_{g = 1}^{G}\;{{n_{g}\left( {{w^{T}\mu_{g}} - {w^{T}\mu}} \right)}\left( {{w^{T}\mu_{g}} - {w^{T}\mu}} \right)^{T}}}{\sum\limits_{g = 1}^{G}{\sum\limits_{{i:\; y_{i}} = g}\;{\left( {{w^{T}x_{i}} - {w^{T}\mu_{g}}} \right)\left( {{w^{T}x_{i}} - {w^{T}\mu_{g}}} \right)}}}}{{{{subject}\mspace{14mu}{to}\mspace{14mu}\mu} = {\sum\limits_{i = 1}^{n}\frac{x_{i}}{n}}},{\mu_{g} = {\sum\limits_{{i:\; u_{i}} = g}^{n}\;\frac{x_{i}}{n_{g}}}}}} & {{Formula}\mspace{14mu} 2} \end{matrix}$

The Mahalanobis' distance is calculated according to Formula 3 in consideration of data correlation and can be used as nonlinear discriminant analysis for determining an associated cluster, based on a closer Mahalanobis' distance from each cluster. In this Formula 3, μ represents a central vector of each cluster, and S⁻¹ represents an inverse matrix of the variance-covariance matrix of the cluster. The central vector is calculated from explanatory variable x, and an average vector, a median value vector, or the like can be used.

$\begin{matrix} {{D\left( {x,\mu} \right)} = \left\{ {\left( {x - \mu} \right)^{l}{S^{- 1}\left( {x - \mu} \right)}} \right\}^{\frac{1}{2}}} & {{Formula}\mspace{14mu} 3} \end{matrix}$

SVM is a discriminant analysis method devised by V. Vapnik (The Nature of Statistical Leaning Theory, Springer, 1995). Particular data points of a data set having known classes are defined as explanatory variables, and classes are defined as objective variables. A boundary plane called hyperplane for correctly classifying the data set into the known classes is determined, and a discriminant for data classification is determined using the boundary plane. Then, the measurement values of a newly offered data set can be substituted as explanatory variables into the discriminant to determine classes. In this respect, the result of the discriminant analysis may be classes, may be a probability of data to be classified into correct classes, or may be the distance from the hyperplane. In SVM, a method of nonlinearly converting a feature vector to a high dimension and performing linear discriminant analysis in the space is known as a method for tackling nonlinear problems. A formula in which an inner product of two factors in a nonlinearly mapped space is expressed only by inputs in their original spaces is called kernel. Examples of the kernel can include a linear kernel, a RBF (radial basis function) kernel, and a Gaussian kernel. While highly dimensional mapping is performed according to the kernel, the optimum discriminant, i.e., a discriminant, can be actually constructed by mere calculation according to the kernel, which avoids calculating features in the mapped space (e.g., Hideki Aso et al., Frontier of Statistical Science 6 “Statistics of pattern recognition and learning—New concepts and approaches”, Iwanami Shoten, Publishers (2004); Nello Cristianini et al., Introduction to SVM, Kyoritsu Shuppan Co., Ltd. (2008)).

C-support vector classification (C-SVC), one type of SVM, comprises preparing a hyperplane by supervising with the explanatory variables of two groups and classifying an unknown data set into either of the groups (C. Cortes et al., 1995, Machine Learning, Vol. 20, p. 273-297).

Exemplary calculation of the C-SVC discriminant that can be used in the method of the present invention will be given below. First, all subjects are divided into two groups, i.e., a liver cancer patient group and a healthy subject group. For example, liver tissue examination can be used for confirming each subject either as a liver cancer patient or as a healthy subject.

Next, a data set consisting of comprehensive gene expression levels of serum-derived samples of the two divided groups (hereinafter, this data set is referred to as a training cohort) is prepared, and a C-SVC discriminant is determined by using genes found to differ clearly in their gene expression levels between the two groups as explanatory variables and this grouping as objective variables (e.g., −1 and +1). An optimizing objective function is represented by Formula 4 wherein e represents all input vectors, y represents an objective variable, a represents a Lagrange's undetermined multiplier vector, Q represents a positive definite matrix, and C represents a parameter for adjusting constrained conditions.

$\begin{matrix} \begin{matrix} \min\limits_{a} & {{\frac{1}{2}a^{T}{Qa}} - {e^{T}a}} \\ {{subject}\mspace{14mu}{to}} & {{{y^{T}a} = 0},{0 \leq a_{i} \leq C},{i = 1},\ldots\mspace{14mu},l,} \end{matrix} & {{Formula}\mspace{14mu} 4} \end{matrix}$

Formula 5 is a finally obtained discriminant, and a group to which the data point is associated can be determined on the basis of the sign of a value obtained according to the discriminant. In this formula, x represents a support vector, y represents a label indicating the association of a group, a represents the corresponding coefficient, b represents a constant term, and K represents a kernel function.

$\begin{matrix} {{f(x)} = {{sgn}\left( {{\sum\limits_{i = 1}^{l}\;{y_{i}a_{i}{K\left( {x_{i},x} \right)}}} + b} \right)}} & {{Formula}\mspace{14mu} 5} \end{matrix}$

For example, a RBF kernel defined by Formula 6 can be used as the kernel function. In this formula, x represents a support vector, and γ represents a kernel parameter for adjusting the complexity of the hyperplane. K(x _(i) ,x _(j))=exp(−r∥x _(i) −x _(j)∥²),r<0  Formula 6

In addition, an approach such as neural network, k-nearest neighbor algorithms, decision trees, or logistic regression analysis can be selected as a method for determining or evaluating the presence and/or absence of expression of a liver cancer-derived target gene in a sample derived from a subject, or for evaluating the expression level thereof by comparison with a control derived from a healthy subject.

The method of the present invention can comprise, for example, the following steps (a), (b), and (c):

(a) measuring an expression level of a target gene in tissues containing liver cancer-derived genes derived from liver cancer patients and/or samples that are already known to contain no liver cancer-derived gene derived from healthy subjects, using the polynucleotide, the kit, or the device (e.g., DNA chip) for detection according to the present invention;

(b) preparing the discriminants of Formulae 1 to 3, 5, and 6 described above from the measurement values of the expression level measured in the step (a); and

(c) measuring an expression level of the target gene in a sample derived from a subject using the polynucleotide, the kit, or the device (e.g., DNA chip) for detection according to the present invention, substituting the obtained measurement value into the discriminants prepared in the step (b), and determining or evaluating the presence and/or absence of the liver cancer-derived target gene in the sample, or evaluating the expression level thereof by comparison with a healthy subject-derived control, on the basis of the obtained results. In this context, in the discriminants of Formulae 1 to 3, 5, and 6, x represents an explanatory variable and includes a value obtained by measuring a polynucleotide selected from the polynucleotides described above in the Section 2, or a fragment thereof, etc. Specifically, the explanatory variable for discriminating a liver cancer patient from a healthy subject according to the present invention is a gene expression level selected from, for example, the following expression levels (1) to (3):

(1) a gene expression level in the serum of a pancreatic cancer patient or a healthy subject measured by any of DNA comprising 15 or more consecutive nucleotides in a nucleotide sequence represented by any of SEQ ID NOs: 1 to 167 and 714 to 729 or a complementary sequence thereof,

(2) a gene expression level in the serum of a pancreatic cancer patient or a healthy subject measured by any of DNA comprising 15 or more consecutive nucleotides in a nucleotide sequence represented by any of SEQ ID NOs: 168 to 183 or a complementary sequence thereof, and

(3) a gene expression level in the serum of a liver cancer patient or a healthy subject measured by any DNA comprising 15 or more consecutive nucleotides in a nucleotide sequence represented by any of SEQ ID NOs: 184 to 224 or a complementary sequence thereof.

As described above, for the method for determining or evaluating the presence and/or absence of a liver cancer-derived gene in a sample derived from a subject, the preparation of a discriminant requires a discriminant prepared in a training cohort. For enhancing the discriminant accuracy of the discriminant, it is necessary for the discriminant to use genes that show clear difference between two groups in the training cohort when preparing the discriminant.

Each gene that is used for an explanatory variable in a discriminant is preferably determined as follows. First, comprehensive gene expression levels of a liver cancer patient group and comprehensive gene expression levels of a healthy subject group, both of which are in a training cohort, are used as a data set, the degree of difference in the expression level of each gene between the two groups is determined through the use of, for example, the P value of t test, which is parametric analysis, or the P value of Mann-Whitney's U test or Wilcoxon test, which is nonparametric analysis.

The gene can be regarded as being statistically significant when the critical rate (significance level) as the P value obtained by the test is smaller than, for example, 5%, 1%, or 0.01%.

In order to correct an increased probability of type I error attributed to the repetition of a test, a method known in the art, for example, Bonferroni or Holm method, can be used for the correction (e.g., Yasushi Nagata et al., “Basics of statistical multiple comparison methods”, Scientist Press Co., Ltd. (2007)). As an example of the Bonferroni correction, for example, the P value obtained by a test is multiplied by the number of repetitions of the test, i.e., the number of genes used in the analysis, and the obtained value can be compared with a desired significance level to suppress a probability of causing type I error in the whole test.

Instead of the statistical test, the absolute value (fold change) of an expression ratio of a median value of each gene expression level between gene expression levels of a liver cancer patient group and gene expression levels of a healthy subject group may be calculated to select a gene that is used for an explanatory variable in a discriminant. Alternatively, ROC curves may be prepared using gene expression levels of a liver cancer patient group and a healthy subject group, and a gene that is used for an explanatory variable in a discriminant can be selected on the basis of an AUROC value.

Next, a discriminant that can be calculated by various methods described above is prepared using any number of genes having large difference in their gene expression levels determined here. Examples of the method for constructing a discriminant that produces the largest discriminant accuracy include a method of constructing a discriminant in every combination of genes that satisfy the significance level of P value, and a method of repetitively evaluating the genes for use in the preparation of a discriminant while increasing the number of genes one by one in a descending order of difference in gene expression level (Furey T S. et al., 2000, Bioinformatics., Vol. 16, p. 906-14). A gene expression level of another independent liver cancer patient or healthy subject is substituted as an explanatory variable into this discriminant to calculate discrimination results of the group to which this independent liver cancer patient or healthy subject belongs. Specifically, the found gene set for diagnosis and the discriminant constructed using the gene set for diagnosis can be evaluated in an independent sample cohort to find a more universal gene set for diagnosis capable of detecting liver cancer and a more universal method for discriminating liver cancer.

Split-sample method is preferably used for evaluating the discriminant performance (generality) of the discriminant. Specifically, a data set is divided into a training cohort and a validation cohort, and gene selection by a statistical test and discriminant preparation are performed using the training cohort. Accuracy, sensitivity, and specificity are calculated using results of discriminating a validation cohort according to the discriminant and a true group to which the validation cohort associates, to evaluate the discriminant performance. On the other hand, instead of dividing a data set, the gene selection by a statistical test and discriminant preparation may be performed using all of samples, and accuracy, sensitivity, and specificity can be calculated by the discriminant analysis using a newly prepared samples cohort for evaluation of the discriminant performance.

The present invention provides a polynucleotide for detection or for disease diagnosis useful in the diagnosis and treatment of liver cancer, a method for detecting liver cancer using the polynucleotide, and a kit and a device for the detection of liver cancer, comprising the polynucleotide. Particularly, in order to select a gene for diagnosis and prepare a discriminant so as to exhibit accuracy beyond a liver cancer diagnosis method using an existing tumor marker CEA, a gene set for diagnosis and a discriminant for the method of the present invention, that exhibit accuracy beyond AFP, CEA, CA19-9 and/or PIVKA-II, can be constructed, for example, by comparing expressed genes in serum derived from a patient confirmed to be negative using AFP, CEA, CA19-9, and/or PIVKA-II but finally found to have liver cancer by detailed examination such as computed tomography using a contrast medium, with genes expressed in serum derived from a patient having no liver cancer.

For example, the gene set for diagnosis is set to any combination selected from one or two or more of the polynucleotides based on a nucleotide sequence represented by any of SEQ ID NOs: 1 to 167 and 714 to 729 or a complementary sequence thereof as described above, optionally one or two or more of the polynucleotides based on a nucleotide sequence represented by any of SEQ ID NOs: 168 to 183 or a complementary sequence thereof, and optionally one or two or more of the polynucleotides based on a nucleotide sequence represented by any of SEQ ID NOs: 184 to 224 or a complementary sequence thereof. Further, a discriminant is constructed using expression levels of the gene set for diagnosis in samples derived from class I liver cancer patients as a result of tissue diagnosis and samples derived from class II healthy subjects as a result of tissue diagnosis. As a result, the presence or absence of liver cancer-derived genes in an unknown sample can be determined with 100% accuracy at the maximum by measuring expression levels of the gene set for diagnosis in an unknown sample.

EXAMPLES

Hereinafter, the present invention is described further specifically with reference to Examples below. However, the scope of the present invention is not intended to be limited by these Examples.

Reference Example 1 Collection of Samples from Liver Cancer Patients and Healthy Subjects

Sera were collected using VENOJECT II vacuum blood collecting tube VP-AS109K60 (Terumo Corp.) from 100 healthy subjects and 34 liver cancer patients (15 cases with stage I, 9 cases with stage II, 5 cases with stage IIIA, 2 cases with stage IIIB, 1 case with stage IIIC, and 2 cases with stage IV) confirmed to have no primary cancer other than liver cancer after acquisition of informed consent, and used as a training cohort. Likewise, sera were collected using VENOJECT II vacuum blood collecting tube VP-AS109K60 (Terumo Corp.) from 50 healthy subjects and 16 liver cancer patients (9 cases with stage I, 5 cases with stage II, and 2 cases with stage IIIA) confirmed to have no primary cancer other than liver cancer after acquisition of informed consent, and used as a validation cohort.

Extraction of Total RNA

Total RNA was obtained from 300 μL of the serum sample obtained from each of 200 persons in total of 150 healthy subjects and 50 liver cancer patients included in the training cohort and the validation cohort, using a reagent for RNA extraction in 3D-Gene® RNA extraction reagent from liquid sample kit (Toray Industries, Inc.) according to the protocol provided by the manufacturer.

Measurement of Gene Expression Level

miRNAs in the total RNA obtained from the serum sample of each of 200 persons in total of 150 healthy subjects and 50 liver cancer patients included in the training cohort and the validation cohort were fluorescently labeled using 3D-Gene® miRNA Labeling kit (Toray Industries, Inc.) according to the protocol (ver 2.20) provided by the manufacturer. The oligo DNA chip used was 3D-Gene® Human miRNA Oligo chip (Toray Industries, Inc.) with attached probes having sequences complementary to 2,555 miRNAs among the miRNAs registered in miRBase Release 20. Hybridization between the miRNAs in the total RNA and the probes on the DNA chip under stringent conditions and washing following the hybridization were performed according to the protocol provided by the manufacturer. The DNA chip was scanned using 3D-Gene® scanner (Toray Industries, Inc.) to obtain images. Fluorescence intensity was digitized using 3D-Gene® Extraction (Toray Industries, Inc.). The digitized fluorescence intensity was converted to a logarithmic value having a base of 2 and used as a gene expression level, from which a blank value was subtracted. A missing value was replaced with a value obtained by subtracting 0.1 from a logarithmic value of the smallest value of the gene expression level in each DNA chip. As a result, the comprehensive gene expression levels of the miRNAs in the sera were obtained for the 150 liver cancer patients and the 150 healthy subjects. Calculation and statistical analysis using the digitized gene expression levels of the miRNAs were carried out using R language 3.0.2 (R Development Core Team (2013). R: A language and environment for statistical computing. R Foundation for Statistical Computing, URL http://www.R-project.org/.) and MASS package 7.3-30 (Venables, W. N. & Ripley, B. D. (2002) Modern Applied Statistics with S. Fourth Edition. Springer, New York. ISBN 0-387-95457-0).

Reference Example 2 Collection of Samples from Patients with Cancers Other than Liver Cancer

Sera were collected using VENOJECT II vacuum blood collecting tube VP-AS109K60 (Terumo Corp.) from each of 72 pancreatic cancer patients, 61 bile duct cancer patients, 38 stomach cancer patients, 25 esophageal cancer patients, 35 colorectal cancer patients, and 16 benign pancreaticobiliary disease patients confirmed to have no cancer in other organs after acquisition of informed consent, and used as a training cohort together with the samples of 35 liver cancer patients and 99 healthy subjects of Reference Example 1. Likewise, sera were collected using VENOJECT II vacuum blood collecting tube VP-AS109K60 (Terumo Corp.) from each of 28 pancreatic cancer patients, 37 bile duct cancer patients, 12 stomach cancer patients, 25 esophageal cancer patients, 15 colorectal cancer patients, and 5 benign pancreaticobiliary disease patients confirmed to have no cancer in other organs after acquisition of informed consent, and used as a validation cohort together with the samples of 17 liver cancer patients confirmed to have no cancer in organs except for liver cancer and 51 healthy subjects of Reference Example 1. Subsequent operations were conducted in the same way as in Reference Example 1.

Example 1 Selection of Gene Marker Using Samples in the Training Cohort, and Method for Evaluating Liver Cancer Discriminant Performance of the Single Gene Marker Using Samples in the Validation Cohort

In this Example, a gene marker for discriminating a liver cancer patient from a healthy subject was selected from the training cohort, and studied in samples of the validation cohort independent of the training cohort, for a method for evaluating liver cancer discriminant performance of each selected gene marker alone.

Specifically, first, the miRNA expression levels in the training cohort and the validation cohort obtained in the above-mentioned Reference Examples were combined and normalized by quantile normalization.

Next, genes for diagnosis were selected in the training cohort. Here, in order to acquire diagnostic markers with higher reliability, only genes having the gene expression level of 2⁶ or higher in 50% or more of the samples in either of the liver cancer patient group in the training cohort or the healthy subject group of the training cohort were selected. In order to further acquire statistically significant genes for discriminating a liver cancer patient group from a healthy subject group, the P value obtained by two-tailed t-test assuming equal variance as to each gene expression level was corrected by the Bonferroni method, and genes that satisfied p<0.01 were acquired as gene markers for use in explanatory variables of a discriminant and described in Table 2.

Among them, genes newly found as markers for examining the presence or absence of liver cancer are polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 167.

A discriminant for determining the presence or absence of liver cancer was further prepared by Fisher's linear discriminant analysis with the expression levels of these genes as an indicator. Specifically, any newly found polynucleotide consisting of a nucleotide sequence represented by any of SEQ ID NOs: 1 to 183 in the training cohort was input to Formula 2 to construct a discriminant. Calculated accuracy, sensitivity, and specificity are shown in Table 3. In this respect, a discriminant coefficient and a constant term are shown in Table 4.

Accuracy, sensitivity, and specificity in the validation cohort were calculated using the discriminant thus prepared, and the discriminant performance of the selected polynucleotides was validated using independent samples (Table 3). For example, the expression level measurement value of the nucleotide sequence represented by SEQ ID NO: 1 was compared between the healthy subjects (100 persons) and the liver cancer patients (34 persons) in the training cohort. As a result, the gene expression level measurement values were found to be significantly lower in the liver cancer patient group than in the healthy subject group (see the left diagram of FIG. 2). These results were also reproducible for the healthy subjects (50 persons) and the liver cancer patients (16 persons) in the validation cohort (see the right diagram of FIG. 2). Likewise, the results obtained about the other polynucleotides shown in SEQ ID NOs: 2 to 183 showed that the gene expression level measurement values were significantly lower (−) or higher (+) in the liver cancer patient group than in the healthy subject group (Table 2). These results were able to be validated in the validation cohort. For example, as for this nucleotide sequence represented by SEQ ID NO: 1, the number of samples that were correctly identified in the detection of liver cancer was calculated using the threshold (7.09) that was set in the training cohort and discriminated between the two groups. As a result, 15 true positives, 49 true negatives, 1 false positive, and 1 false negatives were obtained in the validation cohort. From these values, 97% accuracy, 94% sensitivity, and 98% specificity were obtained as the detection performance. In this way, the detection performance was calculated as to all of the polynucleotides shown in SEQ ID NOs: 1 to 183, and described in Table 3.

Likewise, 72 polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 19, 21, 22, 23, 24, 25, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 39, 40, 41, 43, 44, 45, 46, 47, 48, 50, 51, 54, 55, 56, 57, 58, 60, 61, 62, 63, 64, 65, 68, 73, 80, 86, 88, 91, 93, 94, 99, 114, 117, 170, 171, 172, 173, 174 and 175 exhibited sensitivity of 93.8%, 93.8%, 93.8%, 87.5%, 75%, 87.5%, 62.5%, 81.2%, 93.8%, 93.8%, 75%, 93.8%, 62.5%, 93.8%, 56.2%, 56.2%, 56.2%, 93.8%, 68.8%, 87.5%, 93.8%, 81.2%, 87.5%, 62.5%, 56.2%, 68.8%, 81.2%, 81.2%, 62.5%, 87.5%, 68.8%, 75%, 75%, 75%, 62.5%, 93.8%, 75%, 56.2%, 62.5%, 62.5%, 68.8%, 87.5%, 75%, 62.5%, 75%, 68.8%, 62.5%, 68.8%, 68.8%, 68.8%, 62.5%, 62.5%, 75%, 62.5%, 75%, 68.8%, 56.2%, 81.2%, 68.8%, 56.2%, 62.5%, 56.2%, 56.2%, 68.8%, 56.2%, 62.5%, 87.5%, 87.5%, 75%, 68.8%, 62.5% and 81.2% respectively, in the validation cohort (Table 3). As seen from Comparative Example mentioned later, AFP, which had the highest sensitivity among four existing markers, had sensitivity of 53.3% in the validation cohort (Table 5), demonstrating that, for example, the 72 polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 19, 21, 22, 23, 24, 25, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 39, 40, 41, 43, 44, 45, 46, 47, 48, 50, 51, 54, 55, 56, 57, 58, 60, 61, 62, 63, 64, 65, 68, 73, 80, 86, 88, 91, 93, 94, 99, 114, 117, 170, 171, 172, 173, 174 and 175 can discriminate, each alone, liver cancer in the validation cohort with sensitivity beyond AFP.

Also, for example, 7 polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1, 6, 15, 31, 46, 50, and 58 were able to correctly determine all of the nine stage 1 liver cancer samples contained in the validation cohort to have liver cancer. Thus, these polynucleotides can detect even early liver cancer and contribute to the early diagnosis of liver cancer.

Example 2 Method for Evaluating Liver Cancer Discriminant Performance by Combination of Multiple Gene Markers Using Samples in the Validation Cohort

In this Example, a method for evaluating liver cancer discriminant performance by a combination of the gene markers selected in Example 1 was studied. Specifically, Fisher's linear discriminant analysis was conducted as to 16,533 combinations of two expression level measurement values comprising at least one or more of the expression level measurement values of the newly found polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 167 among the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183 selected in Example 1, to construct a discriminant for determining the presence or absence of liver cancer. Next, accuracy, sensitivity, and specificity in the validation cohort were calculated using the discriminant thus prepared, and the discriminant performance of the selected polynucleotides was validated using the independent samples.

For example, the expression level measurement values of polynucleotides consisting of the nucleotide sequences represented by SEQ ID NO: 1 and SEQ ID NO: 2 were compared between the healthy subjects (100 persons) and the liver cancer patients (34 persons) in the training cohort. As a result, a scatter diagram that significantly separated the expression level measurement values of the liver cancer patient group from those of the healthy subject group was obtained (see the left diagram of FIG. 3). These results were also reproducible for the healthy subjects (50 persons) and the liver cancer patients (16 persons) in the validation cohort (see the right diagram of FIG. 3). Likewise, a scatter diagram that significantly separated the expression level measurement values of the liver cancer patient group from those of the healthy subject group was also obtained as to the other combinations of two expression level measurement values comprising at least one or more of the expression level measurement values of the newly found polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 167 among the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183. These results were able to be validated in the validation cohort. For example, as for these nucleotide sequences represented by SEQ ID NO: 1 and SEQ ID NO: 2, the number of correctly or incorrectly identified samples in the detection of liver cancer was calculated using the function (0=0.77x+y−15.07) that was set in the training cohort and discriminated between the two groups. As a result, 16 true positives, 50 true negatives, 0 false positives, and 0 false negatives were obtained. From these values, 100% accuracy, 100% sensitivity, and 100% specificity were obtained as the detection performance. In this way, the detection performance was calculated for all combinations of two expression level measurement values comprising at least one more of the expression level measurement values of any of the newly found polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 167 among the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183. Among them, 182 combinations comprising the expression level measurement value of the polynucleotide consisting of the nucleotide sequence represented by SEQ ID NO: 1 and the detection performance thereof were described in Table 6 as an example. For example, all of combinations of the expression level measurement values of the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 and 2, SEQ ID NOs: 1 and 3, SEQ ID NOs: 1 and 4, and SEQ ID NOs: 1 and 5 exhibited sensitivity of 100%, 100%, 100%, 94%, and 94%, respectively, in the validation cohort. Likewise, the sensitivity was also calculated as to the combinations of two polynucleotides consisting of the nucleotide sequences represented by SEQ ID NO: 1 and any of SEQ ID NOs: 6 to 251. As a result, all of these combinations exhibited sensitivity of 88% or higher (Table 6), which was beyond the sensitivity (53.3%) of the existing liver cancer marker AFP (Table 5). Thus, a combination of two of the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183 also produced excellent liver cancer detection sensitivity.

In addition, markers for the detection of liver cancer with more excellent sensitivity are obtained by combining the expression level measurement values of 3, 4, 5, 6, 7, 8, 9, 10 or more of the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183. For example, the newly found polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 167 among the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183 selected in Example 1 were measured to obtain their expression levels of the healthy subject group and the liver cancer group in the validation cohort. All of the polynucleotides were ranked in the descending order of their P values based on the Student's t-test which indicate statistical significance of difference between groups (i.e., one having the lowest P value was ranked in the first place), and liver cancer detection sensitivity was evaluated for each of combinations of one or more polynucleotides to which the polynucleotides were added one by one from the top to the bottom according to the rank. In short, the order in terms of SEQ ID NOs in which the polynucleotides were combined in this evaluation is in reverse in terms of SEQ ID NO: 167 to SEQ ID NOs: 166, 165, . . . shown in Table 2 in order. As a result, the sensitivity in the validation cohort was 12.5% for 1 polynucleotide (SEQ ID NO: 167), 43.8% for 2 polynucleotides (SEQ ID NOs: 166 and 167), 68.8% for 4 polynucleotides (SEQ ID NOs: 164 to 167), 87.5% for 6 polynucleotides (SEQ ID NOs: 162 to 167), 93.8% for 10 polynucleotides (SEQ ID NOs: 158 to 167), 100% for 20 polynucleotides (SEQ ID NOs: 148 to 167), 100% for 30 polynucleotides (SEQ ID NOs: 138 to 167), 100% for 50 polynucleotides (SEQ ID NOs: 118 to 167), 100% for 80 polynucleotides (SEQ ID NOs: 88 to 167), 100% for 110 polynucleotides (SEQ ID NOs: 58 to 167), 100% for 150 polynucleotides (SEQ ID NOs: 18 to 167), and 100% for 167 polynucleotides (SEQ ID NOs: 1 to 167).

These results demonstrated that a combination of a plurality of polynucleotides can produce higher liver cancer discriminant performance than that of each polynucleotide alone or a combination of a fewer number of polynucleotides. In this context, the combinations of a plurality of polynucleotides are not limited to the combinations of the polynucleotides added in the order of statistically significant difference as described above, and any combination of a plurality of polynucleotides can be used in the detection of liver cancer.

From these results, it can be concluded that all of the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183 serve as excellent markers for the detection of liver cancer.

Example 3 Selection of Gene Marker Using all Samples and Method for Evaluating Liver Cancer Discriminant Performance of Acquired Gene Marker

In this Example, the samples in the training cohort and the validation cohort used in Examples 1 and 2 were integrated, and selection of a gene marker and evaluation of its liver cancer discriminant performance were conducted using all of the samples.

Specifically, the miRNA expression levels in the serum of the 50 liver cancer patients and the 150 healthy subjects obtained in the above-mentioned Reference Examples were normalized by quantile normalization. In order to acquire diagnostic markers with higher reliability, only genes having a gene expression level of 2⁶ or higher in 50% or more of the samples in either of the liver cancer patient group or the healthy subject group were selected in the gene marker selection. In order to further acquire statistical significance for discriminating a liver cancer patient group from a healthy subject group, the P value obtained by two-tailed t-test assuming equal variance as to each gene expression level was corrected by the Bonferroni method, and genes that satisfied p<0.01 were selected as gene markers for use in explanatory variables of a discriminant. The acquired genes are described in Table 7. In this way, hsa-miR-4688, hsa-miR-4648, hsa-miR-6085, hsa-miR-6126, hsa-miR-6880-5p, hsa-miR-328-5p, hsa-miR-6768-5p, hsa-miR-3180, hsa-miR-6087, hsa-miR-1273g-3p, hsa-miR-1225-5p, hsa-miR-3196, hsa-miR-4695-5p, hsa-miR-6732-5p, hsa-miR-638, hsa-miR-6813-5p, hsa-miR-665, hsa-miR-486-3p, hsa-miR-4466, hsa-miR-30c-1-3p, hsa-miR-3621, hsa-miR-6743-5p, hsa-miR-4298, hsa-miR-4741, hsa-miR-3619-3p, hsa-miR-6824-5p, hsa-miR-5698, hsa-miR-371a-5p, hsa-miR-4488, hsa-miR-1233-5p, hsa-miR-4723-5p, hsa-miR-24-3p, hsa-miR-1238-5p, hsa-miR-4442, hsa-miR-3928-3p, hsa-miR-6716-5p, hsa-miR-6089, hsa-miR-6124, hsa-miR-6778-5p, hsa-miR-557 and hsa-miR-6090 genes represented by SEQ ID NOs: 184 to 224 were found as liver cancer markers relative to the healthy subjects, in addition to the genes described in Table 2. As with the polynucleotides shown in SEQ ID NOs: 1 to 183, the results obtained about the polynucleotides shown in SEQ ID NOs: 184 to 224 also showed that the expression level measurement values were significantly lower (−) or higher (+) in the liver cancer patient group than in the healthy subject group (Table 7). These results were able to be validated in the validation cohort. Thus, the presence or absence of liver cancer in the newly obtained samples can be determined by the methods described in Examples 1 and 2 by using the gene expression level measurement values described in Table 7 either alone or in combination with the gene expression level measurement values described in Table 2.

Example 4 Method for Evaluating Liver Cancer-Specific Discriminant Performance by Combination of Multiple Gene Markers Using Samples in the Validation Cohort

In this Example, novel additional gene markers for diagnosis were selected by comparing gene expression levels of miRNAs in sera of liver cancer patients with those of a control group consisting of healthy subjects, pancreatic cancer patients, bile duct cancer patients, stomach cancer patients, esophageal cancer patients, colorectal cancer patients, and benign pancreaticobiliary disease patients, in the same way as the method described in Example 1, and targeting the training cohort as the sample group described in Reference Example 2. One or two or more markers selected from the group consisting of the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 714 to 729 thus selected and the gene markers selected in Example 1 were used to evaluate liver cancer-specific discriminant performance.

Specifically, first, the miRNA expression levels in the training cohort and the validation cohort obtained in Reference Example 2 mentioned above were combined and normalized by quantile normalization. Next, Fisher's discriminant analysis was conducted as to combinations of 1 to 4 expression level measurement values comprising at least one or more of the expression level measurement values of the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 167 and 714 to 729, to construct a discriminant for determining the presence or absence of liver cancer. Next, accuracy, sensitivity, and specificity in the validation cohort were calculated using the discriminant thus prepared, with the liver cancer patient group as a positive sample group and, on the other hand, the healthy subject group, the pancreatic cancer patient group, the bile duct cancer patient group, the stomach cancer patient group, the esophageal cancer patient group, the colorectal cancer patient group, and the benign pancreaticobiliary disease patient group as negative sample groups. The discriminant performance of the selected polynucleotides was validated using independent samples.

Most of polynucleotides consisting of the nucleotide sequences represented by these SEQ ID NOs (SEQ ID NOs: 1 to 224 and 714 to 729 corresponding to the miRNA markers of Table 1) or complementary sequences thereof mentioned above were able to provide relatively high accuracy, sensitivity, and specificity in the determination of the presence or absence of liver cancer, and furthermore, were able to specifically discriminate liver cancer from other cancers.

The number of the polynucleotides with cancer type specificity in the combination mentioned above can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more for the combination. The combinations of 4 or more polynucleotides were able to exhibit discriminant accuracy of 90% or higher.

Comparative Example 1 Liver Cancer Discriminant Performance of Existing Tumor Marker in Blood

The concentrations of the existing tumor markers AFP, CEA, CA19-9, and PIVKA-II for detecting liver cancer in blood were measured in the training cohort and the validation cohort obtained in Reference Example 1. When the concentrations of these tumor markers in blood are higher than the reference values described in Non-Patent Literature 5 (AFP: 10 ng/mL, CEA: 5 ng/mL, CA19-9: 37 U/mL, PIVKA-II: 40 mAU/mL), subjects are usually suspected of having cancer. Thus, whether or not the concentration of each tumor marker in blood exceeded its reference value was determined for each sample, and the results were assessed for the ability of these tumor markers to detect cancer in liver cancer patients. The sensitivity of each existing marker in the training cohort and the validation cohort was calculated. The results are shown in Table 5. The sensitivity of AFP, which had the highest sensitivity among the 4 existing tumor markers measured, was as low as 56.3% in the training cohort, and was as low as 53.3% in the validation cohort, demonstrating that neither of the markers are useful in the detection of liver cancer (Table 5).

On the other hand, as shown above in Tables 3 and 6 of Examples 1 and 2, it can be concluded that all of the polynucleotides consisting of the nucleotide sequences represented by SEQ ID NOs: 1 to 183 have combinations of 1 or 2 polynucleotides exhibiting sensitivity beyond the existing liver cancer markers and thus serve as excellent diagnosis markers.

As shown in these Examples and Comparative Example, the kit, etc., and the method of the present invention can detect liver cancer with higher sensitivity than the existing tumor markers and therefore permit early detection of liver cancer. As a result, surgical resection having high potentiality of radical cure can be applied, leading to drastic improvement in survival rate.
